Filter by:This was a phase 1/2, open-label, dose-escalation study of arginine deiminase linked via succinimidyl succinate to polyethylene glycol of 20,000 molecular weight (ADI-PEG 20) in subjects with advanced melanoma. ADI-PEG 20 was administered intramuscularly (IM) at escalating doses weekly for 9 weeks (cycle 1) or 8 weeks (subsequent cycles). The primary objectives were to the establish the safety, tolerability, and clinical efficacy of ADI-PEG 20. Secondary objectives included evaluation of the metabolic activity by [18F]-fluorodeoxyglucose positron emission tomography (FDG PET), pharmacodynamics, correlation of immunogenicity with clinical response, and correlation of argininosuccinate synthetase (ASS) tumor expression with clinical response.
Background: - Human peripheral blood lymphocytes have been engineered to express a T-cell receptor (TCR) that recognizes a blood type,HLA-A 0201 (human leukocyte antigen) derived from the gp100 protein. A retroviral vector was constructed that can deliver the T-cell receptor (TCR) to cells. - Patients' cells will be converted into cells able to recognize and fight melanoma tumors. Objectives: - To determine whether TCR-engineered lymphocytes can be put in cells removed from patients' tumors or blood and then reinfused, with the purpose of shrinking tumors. - To evaluate safety and effectiveness of the treatment. Eligibility: - Patients 18 years of age or older with metastatic cancer melanoma (cancer that has spread beyond the original site). - Patient's leukocyte antigen type is HLA-A 0201. Design: -Patients undergo the following procedures: - Leukapheresis (on two occasions). This is a method of collecting large numbers of white blood cells. The cells obtained in the first leukapheresis procedure are grown in the laboratory, and the anti-MART-1 protein is inserted into the cells using an inactivated (harmless) virus in a process called retroviral transduction. Cells collected in the second leukapheresis procedure are used to evaluate the effectiveness of the study treatment. - Chemotherapy. Patients are given chemotherapy through a vein (intravenously, IV) over 1 hour for 2 days to suppress the immune system so that the patient's immune cells do not interfere with the treatment. - Treatment with anti-melanoma antigen recognized by T-cells (MART)-1. Patients receive an intravenous (IV) infusion of the treated cells containing anti-MART-1 protein, followed by infusions of a drug called IL-2 (aldesleukin), which helps boost the effectiveness of the treated white cells. - Patients are given support medications to prevent complications such as infections. - Patients may undergo a tumor biopsy (removal of a small piece of tumor tissue). - Patients are evaluated with laboratory tests and imaging tests, such as CT (computed tomography) scans, 4 to 6 weeks after treatment and then once a month for 3 to 4 months to determine the response to treatment. - Patients have blood tests at 3, 6, and 12 months and then annually for 5 years.
Photosensitivity of the skin to UVA and UVB will be determined
The goal of this clinical research study is to evaluate the use of an imaging technology called spectral diagnosis. Researchers want to find out if a special spectral-diagnosis probe can be used to detect skin cancers.
The goal of this clinical research study is to evaluate an experimental imaging technology, the multispectral digital microscope (MDM), which may help doctors see how far skin cancer extends (widens out) on an area of skin. Researchers want to learn if this new technology can help doctors identify the exact areas involved in precancerous or cancerous changes in the skin.
RATIONALE: Understanding why sunbathers use or don't use sunless tanning products may help doctors plan effective ways to prevent skin cancer caused by sunbathing. PURPOSE: This phase I/II trial is studying attitudes about the use of sunless tanning products and how well sunless tanning products work as a substitute for sunbathing in healthy participants.
Mohs Micrographic Surgery is a well established method for treatment of cutaneous malignancies. Part of this technique requires marking skin surrounding the tumor. There are two ways of marking the tissue, lightly scoring it with a scalpel or marking it with a surgical marker. This study is to determine if there is a noticeable difference in outcome between patients who have their tissue lightly scored with a scalpel or marked with a surgical marking pen.
Purpose of the project is to develop a school-based intervention aimed at increasing hat use when children are outside at home and at school. The intervention is targeted to fourth grade children in Hillsborough County, Florida and is based on Theory of Reasoned Action and Planned Behavior. It is structured to accomplish the following goals: (a) increase sun protection knowledge of children in regards to hat use,(b) foster more positive attitudes in regard to wearing hats,(c) change the subjective norms of wearing hats (d) target persons that children perceive as controlling their behavior of wearing hats(parents,teachers) and increase the use of hats when children are outdoors at school(primary outcome) and when outdoors at times other than school(secondary outcome).
The primary objective of the trial is to determine, in patients who have undergone surgery with curative intent for high-risk CSCC of the head and neck, whether there is a difference in time to loco-regional relapse between patients treated with post-operative concurrent chemo-radiotherapy ,consisting of Carboplatin, and post-operative radiotherapy alone. The target sample size for the trial is 266 patients and will take 3-4 years to accrue, based on an anticipated accrual of 80 patients/year. A further 2 years follow up is required.
In a population of kidney transplant recipients having developed a first squamous cell carcinoma, the aim of the study is to assess the incidence of subsequent skin cancers over 2 years in patients who are switched to rapamycin as compared to patients who are maintained under calcineurin inhibitors.
